What is the difference between SCDJWS 5.0 (CX-310-230) and SCDJWS 5.0 (CX-310-220) .
I had a look on the syllabus contents ,i think only difference i found is that
SCDJWS 5.0 (CX-310-230) is having JAX-RPC and SCDJWS 5.0 (CX-310-220) is having JAX-WS.

Actually while preparing for SCDJWS 5.0 i refered study material of SCDJWS 5.0 (CX-310-220),but i am planning to give exam for SCDJWS 5.0 (CX-310-230) ,do i need to invest a alot for preparing for SCDJWS 5.0 (CX-310-230) or as i mentioned the only difference is
of JAX-RPC and JAX-WS.
